ABSTRACT:
A multiaxis actuator is described which provides force along at least two translational axes through the interaction of multiple windings on a single platen which interact with the field poles of a magnetic member spaced apart a sufficient distance to allow multiaxis operation. Said field poles generate magnetic lines of flux perpendicular to said platen. Said windings are constructed and arranged so as to provide current paths in one direction over a generally wide planar area intercepting the magnetic flux lines, while concentrating current in the opposite direction return path in a relatively narrow volume not intercepting the magnetic flux lines. Said individual windings are utilized in pairs having their substantially planar portions collinear to one another and disposed substantially perpendicular to a portion of the magnetic field lines generated between said field poles. Pairs of such windings so arranged may be mounted on both sides of said platen such that current flowing in a first pair of windings flows in a direction which is disposed transverse of the direction of current flowing in an opposite pair of such windings. Windings so disposed will generate force perpendicular to lines of force generated by said poles and perpendicular to direction of current flow. A wide gap between the poles of the magnetic member allows translational or rotational motion of the platen relative to the field poles without affecting generated force.
